What does the term charter refer to?

The term charter specifically refers to a flight arrangement where an aircraft and its crew are leased by a group or company for a specific trip or purpose, rather than those flights being part of a regularly scheduled airline service. This option allows for flexibility in scheduling, routing, and accommodating specific needs of the group. Charter flights can be used for various purposes including corporate travel, tourism, and special events, often providing a tailored experience that is distinct from regular commercial flights.

In contrast, regularly scheduled flights, as mentioned in the first option, are planned by airlines to fly on a set timetable with available seats for multiple passengers. The third option suggests a low-cost ticket option, which does not capture the essence of charter flights, as those are about the exclusive use of the aircraft and crew rather than pricing. The fourth option applies to specific scenarios that might be considered private flights, but does not encompass the broader definition of charter flights, which can serve various groups and purposes beyond just the corporate sector.
